What to do?
I bought a M3 this summer with the 18"OEM wheels. I had a 535i with the sports package before and was using the Dunlop sport 3D 245/40/R18 XL on4 wheels that I can no longer use, however the tires are in great shape.
So my options are:
Buy 4 A7 wheels with the TPS...but I don't like the fit in the back
Buy 2 rear tires 255/40/R18 Dunlop 3D Winter sport and fit them on the 18"OEM wheels.
Just keep the 4 winter tires that I have and put them on the OEM wheels, I think that they would fit on the 9.5" rear wheels, however it's pretty stretched...
Or just try to sell the 4 tires...won't get much fot it and buy the 4 pirelli's...
